DETAILED DESCRIPTION OF THE INVENTION

The embodiments of the invention will be apparent from the following detailed description, which proceeds with reference to the accompanying drawings, wherein the same references relate to the same elements.

Referring to FIG. 1A to FIG. 1F, FIG. 1A is a schematic top view showing a display panel 1 according to the embodiment of the invention. FIG. 1B is a sectional view along line A-A in FIG. 1A. FIG. 1C is a schematic bottom view showing the display panel in FIG. 1B. FIG. 1D and FIG. 1E are sectional views respectively along line B1-B1 and line B2-B2 in FIG. 1C. FIG. 1F is an enlarged schematic view showing the zone C in FIG. 1C.

In FIG. 1B, the display panel 1 includes a first substrate 11, a second substrate 12 and a display medium layer 13. In addition, the display panel 1 further includes a light shielding layer 14, a filter layer and a protection layer 18. In FIG. 1A, FIG. 1C, FIG. 1D and FIG. 1E, the second substrate 12, the display medium layer 13 and the protection layer 18 are not shown. Besides, a first direction D1, a second direction D2 and a third direction D3 are shown in the figure, and the first direction D1, the second direction D2 and the third direction D3 are substantially perpendicular to each other. The first direction D1 can be substantially parallel to the extension direction of the data line. The second direction D2 can be substantially parallel to the extension direction of the scan line. The third direction D3 is another direction which is substantially perpendicular to the first direction D1 and the second direction D2.

The first substrate 11 is disposed opposite to the second substrate 12. The display medium layer 13 is sandwiched between the first substrate 11 and the second substrate 12. The display panel 1 can be an LCD (liquid crystal display) panel or an OLED (Organic Light-Emitting Diode) display panel. Here, the display panel 1 is the LCD panel for example, and the display medium layer 13 is a liquid crystal layer. Alternatively, if the display panel 1 is an OLED display device, the display medium layer 13 can be an organic light emitting layer, and the first substrate 11 can be a cover plate to protect the organic light emitting layer from external moisture or particle pollution. The first substrate 11 or the second substrate 12 can be made of transparent material, for example, glass, quartz or the like, plastic, rubber, fiberglass, or other polymer material; alternatively, the first substrate 11 or the second substrate 12 can be made of opaque material, for example metal-fiberglass composite plate, metal-ceramic composite plate, printed circuit board, or other material. In the embodiment, the material of the first substrate 11 or the second substrate 12 is transparent glass for example.

The light shielding layer 14 and the filter layer are disposed on the first substrate 11. In the embodiment, the light shielding layer 14 and the filter layer are included in a color filter array disposed on the first substrate 11, so the first substrate 11 with the color filter array becomes a color filter substrate. In addition, a TFT (thin film transistor) array can be disposed on the second substrate 12, so the second substrate 12 with the TFT array becomes a TFT substrate. Alternatively in other embodiments, the light shielding layer 14 and/or the filter layer may be respectively disposed on the second substrate 12, so it becomes a BOA (black matrix on array) substrate or becomes a COA (color filter on array) substrate, and it is not limited thereto.

The light shielding layer 14 includes a plurality of openings O. The openings O are the regions which the light could be transmitted (the region other than the opening O is light shielding layer 14). The light shielding layer 14 can be a black matrix and made of opaque material, for example metal or resin. For example, metal can be chromium, chromic hydroxide, or nitrogen oxide chromium compounds. Because the light shielding layer 14 is opaque, it forms an opaque region on the substrate 11 to further define a region with light transmittance. Referring to FIG. 1C, the openings O includes a first opening O1 adjacent to a first edge 111 of the first substrate 11 and a second opening O2 adjacent to the first opening O1. In the embodiment, among the openings O of the shielding layer 14, the first opening O1 and the second opening O2 are the adjacent openings closest to the first edge 111 of the first substrate 11. The dimensions of the first opening O1 and the second opening O2 are relatively smaller than other openings O that are not closest to the first edge 111 of the first substrate 11.

Besides, the filter in the embodiment for example but not limited to includes color blocks in three kinds of colors which are arranged repeatedly (R represents red color, G represents green color and B represents blue color in the figure). Its material can be transparent material for example pigment or dye. The filter layer can include a first color block 15 and a second color block 16 adjacent to the first color block 15. The first color block 15 and the second color block 16 have different colors. In the embodiment for example, the first color block 15 is red R, the second color block 16 is green G, but they are not limited thereto. The first color block 15 and the second color block 16 are respectively disposed along a first direction D1 and cover partial of the light shielding layer 14. In manufacturing process, after forming the light shielding layer 14 having a plurality of openings O on the first substrate 11, along the first direction D1 the first color block 15 and the second color block 16 are respectively formed on the light shielding layer 14. Thus, the first opening O1 is filled with partial of the first color block 15 along the first direction D1 and the first color block 15 overlaps partial of the shielding layer 14, and the second opening O2 is filled with partial of the second color block 16 along the first direction D1 and the second color block 16 overlaps partial of the shielding layer 14.

The first color block 15 overlaps partial of the shielding layer 14. Thus, the first color block 15 on the shielding layer 14 has a first overlap portion 151 closest to the first edge 111 (the first overlap portion 151 is adjacent and connected to the first opening O1, the side of the first opening O1 closest to the first edge 111 has a tangent line parallel to the first edge 111, and the tangent line also acts as a virtual border of the first overlap portion 151). The second color block 16 overlaps partial of the shielding layer 14. Thus, the second color block 16 on the shielding layer 14 has a second overlap portion 161 closest to the first edge 111 (the second overlap portion 161 is adjacent and connected to the second opening O2, and the side of the second opening O2 closest to the first edge 111 has a tangent line parallel to the first edge 111, and the tangent line also acts as a virtual border of the second overlap portion 161). Referring to FIG. 1F, the area of the first overlap portion 151 and the area of the second overlap portion 161 are different. Here, the area of the first overlap portion 151 is smaller than the area of the second overlap portion 161.

In other words, in the embodiment, as to the same color block (for example color block R), it forms a plurality of overlap portions when disposed on the light shielding layer 14. The overlap portion closest to the first edge 111 is regarded as the first overlap portion 151. Similarly, as to color block G, it also forms a plurality of overlap portions when disposed on the light shielding layer 14. The overlap portion closest to the first edge 111 is regarded as the second overlap portion 161. Because the area of the first overlap portion 151 is different from the area of the second overlap portion 161, a heterogeneous edge is formed. In addition, referring to FIG. 1D and FIG. 1E, along the first direction D1, there is a first shortest distance d1 between the first overlap portion 151 and the first edge 111, there is a second shortest distance d2 between the second overlap portion 161 and the first edge 111, and the first shortest distance d1 and the second shortest distance d2 are different. Here, the first shortest distance d1 is greater than the second shortest distance d2. Therefore, in this embodiment, the edge of the first color block 15 and the second color block 16 closet to the first edge 111 of the first substrate 11 are not aligned evenly and thus to form a heterogeneous boundary. It is easier to block external particle or moisture from entering the display panel 1 through the edge of the color block. It prevents the pollution by external particle, and therefore raises product reliability and competitiveness.

Besides, referring to FIG. 1D, the thickness of the first overlap portion 151 is thinner than the thickness of the partial of the first color block 15 at the first opening O1. In one embodiment for example, the thickness of the first overlap portion 151 is about 1.1 μm, and the thickness of the first color block 15 at the first opening O1 is about 1.8 μm. Similarly, the thickness of the second overlap portion 161 is also thinner than the thickness of the partial of the second color block 16 at the second opening O2. Therefore, the filter layer has better flatness.

Besides, as to the same color block, when the ratio of the area of the overlap portion closest to the first edge 111 of the first substrate 11 with respect to the area of the first opening O1 is within a specific range, an adhesion between the color block and the light shielding layer 14 can be increased (if the ratio is too high, it can not form the heterogeneous edge to block external particle; if the ratio is too low, the reliability is poor). In the embodiment, the ratio of the area of the first overlap portion 151 to the area of the first opening O1 is between 0.3 and 1.2. Here, the area of the first opening O1 is equal to the projected area of the first color block 15 which the first opening O1 is filled with.

Referring to FIG. 1C again, the openings O of the light shielding layer 14 further includes a third opening O3 relatively away from the first edge 111 along the first direction D1. The third opening O3 is filled with partial of the first color block 15, and the area of the third opening O3 is greater than the area of the first opening O1. Here, the area of the third opening O3 greater than the area of the first opening O1 means that: the projected area of the first color block 15 which the third opening O3 is filled with is greater than the projected area of the first color block 15 which the first opening O1 is filled with. FIG. 1C shows that the third opening O3 and the first opening O1 are adjacent openings. Alternatively, the third opening O3 may be toward the first direction D1 and it is not adjacent to the first opening O1, and it is not limited thereto.

Besides, in the embodiment, the first color block 15 overlaps the light shielding layer 14 and has a third overlap portion 152. The second color block 16 overlaps the light shielding layer 14 and has a fourth overlap portion 162. The first overlap portion 151 is located between the third overlap portion 152 and the first edge 111. The second overlap portion 161 is located between the fourth overlap portion 162 and the first edge 111. In addition, a spacer S can disposed across the third overlap portion 152 and the fourth overlap portion 162. The material of the spacer S can be resin, silicate, fiberglass, or other photosensitive resist material, and it is not limited thereto. The spacer S keeps an interval between the first substrate 11 and the second substrate 12, so as to supply the accommodation space filled by the liquid crystal molecules. In the embodiment, the overlap area between the spacer S and the third overlap portion 152 is different from the overlap area between the spacer S and the fourth overlap portion 162. Here, the overlap area between the spacer S and the third overlap portion 152 is greater than the overlap area between the spacer S and the fourth overlap portion 162. In addition, although FIG. 1C only shows one spacer S, actually, the display panel 1 has a plurality of the spacers S.

Besides, the first substrate 11 further includes a second edge 112 connecting to the first edge 111. The color filter layer further includes a third color block 17 closest to the second edge 112. The term “closest to” means that there is no other color block between the third color block 17 and the second edge 112. The color of the third color block 17 may be the same with or different from that of the first color block 15 or the second color block 16. The third color block 17 is disposed on the light shielding layer 14 along the direction D1. Although the third color block 17 closest to the second edge 112 is disposed, the third color block 17 will not be seen when overlooking the first substrate 11 because the third color block 17 is not injected into any opening O. But as shown in FIG. 1C, the third color block 17 is seen when looking up and seeing the first substrate 11. Along the second direction D2, there is a third shortest distance d3 from the portion of the third color block 17 corresponding to the first opening O1 to the second edge 112. Along a second direction D2, there is a fourth shortest distance d4 from the portion of the third color block 17 corresponding to the third opening O3 to the second edge 112. The third shortest distance d3 is different from the fourth shortest distance d4. Thus similarly, the edge of the third color block 17 closest to the second edge 112 is also not aligned evenly. Thus, the edge of the third color block 17 also forms a heterogeneous boundary. It is easier to block external particle or moisture from entering the display panel 1 through the edge of the third color block 17. Therefore it raises product reliability.

Besides, referring to FIG. 1B again, the protection layer 18 (for example over-coating) can cover the light shielding layer 14 and the color filter layer. The material of the protection layer 18 can be photoresist, resin material, or inorganic materials (for example SiOx/SiNx), etc. to protect the light shielding layer 14 and the color filter layer from damage due to follow-up manufacturing process. In addition, the display panel 1 further includes a sealant (not shown in the figure). The sealant is disposed between the first substrate 11 and the second substrate 12 to enclose the peripheral between the first substrate 11 and the second substrate 12. The sealant is disposed corresponding to the periphery light shielding layer 14 of the display panel 1. Thus, when looking down the display panel 1, the sealant is covered by the light shielding layer 14. The sealant may be light curing adhesive (for example UV curing adhesive) and it is applied to and surrounds the fringes of display area between the first substrate 11 and the second substrate 12 for example but not limited to. In addition, the sealant, the first substrate 11 and the second substrate 12 may form an accommodation space (not shown in the figure), and the display medium layer 13 can be disposed in the accommodation space. Here, for example but not limited to, ODF (one drop filling) is utilized to fill the accommodation space enclosed by the sealant with the liquid crystal molecules.

In addition, the display panel 1 may further includes a plurality of scan lines and a plurality of data lines (no shown in the figure). The scan lines and the data lines are interlaced to define a plurality of pixels. Therefore, when the scan lines of the display panel 1 receive a scan signal, the TFTs corresponding to the respective scan lines are accordingly conducted and data signals corresponding to the respective pixel of column are transmitted to the corresponding pixels by the data lines. Thus the display panel 1 can display image screen.

Referring to FIG. 2, it is a schematic bottom view showing a display panel 1 a according to another embodiment of the invention. Here, only the first color block 15 a and the second color block 16 a of the color filter layer are shown in the display panel 1 a in FIG. 2. Other color blocks, the second substrate 12, the display medium layer 13 and the protection layer 18 are also not shown.

The display panel 1 a has the same elements and features with those of the display panel 1. However, the difference from the display panel 1 in FIG. 1C is that along the third direction D3, the first overlap portion 151 of the first color block 15 a and the second overlap portion 161 of the second color block 16 a connects to form a concave portion U (namely, along the third direction D3, an interval exist between the first overlap portion 151 and the second overlap portion 161). There is a first longest distance d5 from the concave portion U to the first edge 111 along the first direction D1, there is a fifth shortest distance d6 from the first color block 15 a or the second color block 16 a to the first edge 111. Here, it shows that the ratio of the difference between the first longest distance d5 and the fifth shortest distance d6 with respect to the length of the first opening O1 is between 0.05 and 0.5. The length of the first opening O1 means the maximum length of the first opening O1 along the first direction D1. The concave portion U (namely, the interval between the two) formed by the first overlap portion 151 and the second overlap portion 161 form a heterogeneous boundary at the edge of the color filter layer. Further, when the sealant is disposed here (the edge of the filter layer), it increases the contact area of the sealant and the color filter layer thus to enhance the adhesion property of the seal agent and the color filter layer.

Besides, the technique features of other elements of the display panel 1 a can refer to those of the display device 1, they are not repeated here again.

Besides, Referring to FIG. 3, it is a schematic view showing a display panel 2 according to the embodiment of the invention.

The display device 2 includes a display panel 3 and a backlight module 4. The display panel 3 and the backlight module 4 are disposed opposite to each other. The display device 2 in the embodiment is an LCD device, and the display panel 3 employs one of the above mentioned display panel 1, 1 a, or other various implementation. Because specific technique contents can refer to the above, they are not repeated here again. When the light beam E emitted from the backlight module 4 passes through the display panel 3, it displays colors to form an image by each pixel of the display panel 3.

As mentioned above, as to the display panel, the first color block and its adjacent second color block are respectively disposed on the light shielding layer along the first direction. The first opening is filled with partial of the first color block, and the first color block overlaps partial of the light shielding layer. The second opening is filled with partial of the second color block, and the second color block overlaps partial of the light shielding layer. The area of the first overlap portion of the first color block closest to the first edge on the light shielding layer is different from the area of the second overlap portion of the second color block closest to the first edge on the light shielding layer; alternatively, the first shortest distance of the first overlap portion to the first edge is different from the second shortest distance of the second overlap portion to the first edge; alternatively, the third color block closest to the second edge is disposed on the light shielding layer along the first direction. Along the second direction substantially perpendicular to the first direction, the shortest distance from the portion of the third color block corresponding to the first opening to the second edge is different from the shortest distance from the portion of the third color block corresponding to the third opening to the second edge. Therefore, the border between the light shielding layer and the color block of the display panel is not aligned evenly. It can form a heterogeneous boundary to block the external particle or moisture from entering the panel through the border between the light shielding layer and the color block. It prevent the display panel from the pollution by external particle, and therefore raises product reliability and competitiveness.
